Off-Network Control Processing for Scalable Routing. Edition No. 1
VDM Publishing House, June 2009, Pages: 164
In this book we investigate two problems concerning
wireless sensor networks: (A) energy efficient medium
access control and (B) scalable routing architecture
for very large wireless sensor networks. Regarding to
the first problem , we propose a Self Reorganizing
Slot Allocation (SRSA) mechanism for a TDMA-based
medium access control (MAC) protocol. The primary
contribution is to demonstrate that with adaptive
slot allocation algorithms, it is possible to
minimize such interference under low traffic loading
conditions. The second contribution is to design a
feedback-based adaptive allocation protocol that can
minimize those interferences without relying on any
global synchronization mechanism. In the second
problem, we develop a routing solution Off-Network
Control Processing (ONCP) for sensor networks. A
tiered hybrid routing approach, consisting of “coarse
grain” server-based global routing, and distributed
“fine grain” local routing is proposed for achieving
scalability by avoiding network-wide control message
dissemination. We present the ONCP architectural
concepts and analytically characterize its
performance in relations to both flat and
hierarchical routing architectures.
